me i e new Patented Aug. 6, 1957 7 Referring more particularly to Figs.1 to of the drawings, reference numeral l designates a lamp housing 1Claim. (Cl. 240-78) This invention relates generally to recessedlighting fix tu-res.

Lighting fixtures of the prior art utilizing an assembly consisting of apanel removably secured to a lamp housing, a junction box rigidlysecured tothe panel, and a lamp socket-which is rigidly secured to thepanel, this The box 1 is provided with a closure comprising a' metalframe 8 to which a transparent glass panel 9 is secured, as by clips 10.The frame 8 is pivotally secured to the flange 2, as by hing-es 11, sothat the closure may be dropped to a vertical or other posit-ion whenaccess to assemblyv being removable as a unit from the lamp housing forrepair or inspection purposes.

The aforesaid components present a somewhat cumbersomeand heavyassembly, which isnot onlydifficult to assemble, but is somewhatdifiicult to manipulate as a unit, and is also objectionable in that itimposes a fairly heavy load on the panel, which supports the weight of iall the components.

The present invention has, as its primary object, an arrangement of theaforesaid components which renders the components readily'removable fromthe lamp housing for access, repair or inspection purposes, whilerelieving the panel of the load of the junction box, lamp socket, lampand elements which interconnect the junction box with the lamp socket.

Another object of the invention is to provide a lighting A furtherobject of the invention is to provide a V lighting fixture of thecharacter described, in which heat transmission from the lamp socket,lamp and lamp housing to the panel, and from the panel to the junctionbox is reduced to a minimum.

A still further object of the invention is to provide novel means forsupporting the slidable pane-l in its normal position in the lamphousing.

Qthcr objects and advantages of my invention will be apparent during thecourse of the following description.

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like par-ts throughout thesame,

.Fig. 1 is a fragmentary cross-sectional view, showing the principalfeatures of the invention;

Fig. 2 is a cross-sectional view, taken on the line 2-2 of Fig. 1;

Fig. 3 is a fragmentary cross-sectional view, taken on the line 33 ofFig. 1;

Fig. 5 is a fragmentary cross-sectional view, taken on the line 55 ofFig. 2;

Fig. 6 is a fragmentary view, simil-ar'to Fig. 2, but showing amodification of the invention;

Fig. 7 is a fragmentary cross-sectional view, taken on the line 77 ofFig. 6;

Fig. 8 is a view similar to Fig. 1, but showing another modification ofthe invention, and

Fig. 9 is a cross-sectional view, taken on the line 9-9 of Fig. 8.

the interior of the box 1 is desired, and is normally maintained in theclosed position shown by means of a screw 12 which is secured to theframe 8 and may be threaded into a socket 13,:which is secured in theflange 2.

Removably secured to the top wall or ceiling of the box 1, as by sheetmetal screws 14 (see Figs. 1 and 3), is a U-shapedbracket 15, whichdepends into the box, and to which is spot welded a bracket 16, providedat one end with a depending flange 17, the intermediate portion of whichis bent to provide a recess 18, for a purpose to be presently described.

Secured to, the flange 17 of the bracket 16, as by screws 19, is thebase portion 20 of a lamp socket 21, in which the bulb 22 is mounted. Areflector 23 is secured to the bracket 16, just above the bulb 22, as bya screw 24.

Rigidly secured to the flange 17 of the bracket 16, as

by a nut 25, is a conduit 26 which extends outside thelamp housing 1through a rectangular opening 27 in a side wall 28 of the housing. Thenut 25 is disposed in the recess 18 of the flange 17 and is thus spacedfrom the base 20 of the lamp socket.

The conduit 26 is secured to and supports a conventional junction box29, having a removable cover 30. The conduit 26 is secured to andsupports a conventional junction box 29, having a removable cover 30.The conduit 26 carries the wires 31 and 32 from the junction box to thelamp socket 21, and connection to these wires is made, in the customaryway, inside the junction box, from B cable 33.

A panel or closure 34 is provided for the opening 27. This panelcomprises a rectangular plate, which is slidable in guides or tracksprovided between the wall 28 of the housing 1 and angles 35 and 36 whichare welded to the side walls 37 and 38 respectively of the housing (seeFig. 5). The plate 34 is supported in operative position by means oflugs 39 which are pivotally secured to the flange 2, as by screws 40(see Fig. 4). The plate 34 is also provided in its upper edge with anelongated recess 41 for the purpose of enabling the plate to clear theconduit 26 when the plate is slid upwardly to its operative position.

When it is desired to gain access to the junction box 29 for inspectionor other purposes, the closure 8 is A dropped to a vertical position, inthe manner previously described, the lugs 39 are turned about theirpivots to release the panel 34, and the panel is slid downwardly andremoved from the lamp housing. The lamp 22 is removed from the socket21, and the screws 14 then removed, permitting the brackets 15 and 16,lamp socket 20-21, conduit 26, and junction box 29 to be withdrawn as aunit to a position in which the inspector can easily remove the cover 30and inspect to junction box. In the course of such withdrawal, the box29 is passed through the opening 27 to a position inside the housing 1,this being permitted by virtue of the flexibility and length of thecable 33.

It is thus seen that I have provided an arrangement of the componentswhich is readily removable from the lamp housing for access, repair orinspection purposes. At the same time, the panel 34 is relieved of theload'of the junction box, lamp socket, lamp, andrint'erconneob' ingelements which include the conduit 26 and bracket 16. Furthermore, aunique means has been provided for closing the opening 27, in the formof a closure plate or panel which is slid into operative position, ismaintained in operative position by the lugs 39, and is with drawablefrom such position by gravity of its own weight.

The panel 34 is effective to prevent transmission of heat from theinterior of the lamp housing, to the junction box 29,, and the.transmission of heat from y the plate 34 to the conduit 26 is virtuallynegligible,.since the conduit has virtually no contact with this plate.Moreover, transmission of heat from the lamp to the housing. 1 isreduced to a minimum, by virtue of the fact that the only attachment ofparts inside the housing with the inner wall of said housing is throughthe bracket 15.

In Figs. 6 and 7, a modification is shown, in which the plate 34,instead of being maintained in operative posi: tion by lugs 39, ismaintained in position by means of a single screw 42 which extendsthrough: the plate 34 and intothe wall 28 of the lamp housing.

In Figs. 8 and 9, a modification is shown, inwhich the screws 19, to theflange 45 of a bracket 46, which is supported by the top of the box 1 inthe same manner that the bracket 16 of the previously described form ofthe invention is supported, so that further description thereof isbelieved unnecessary.

In this case, removal of the junction box 29 for' inspection or otherpurpose, is accomplished by first removing the bracket 46, after whichaccess to the screws 44 may be had, these screws removed, the plate 34removed, and

the junction box then passed through the opening 27 into the lamphousing 1.

tial air gap between the nut 43 and the flange 45 of the bracket 46.

It is to be understood that the forms of my invention, herewith shownand described, are to be taken as preferred examples of the same, andthat various changes in the shape, size, and arrangement of parts may beresorted to, without departing from the spirit of my invention, or thescope of the subjoined claim.

Having thus described my invention, I claim:

A lighting fixture of the wall-recessed type comprising a housing'havinga side wall and an opening therein, a

panel normally closing said opening and removable to expose saidopening, means detachably connecting said panel. with said housing, lampsocket means supported on another wall of said housing, a junction boxdisposed externally of the housing opposite said opening and providedwith means connecting it with said lamp socket means for supporttherefrom and unitary movement therewith, said junction box having aremovable closure, and wiring from said junction box to said socketmeans and including connections within said junction box adapted to beexposed within said housing when said socket means and junction box areunitarily moved into the housing, the said housing opening normallyclosed by the panel being of sutficient dimension to pass the junctionbox to expose its closure upon the occasion of such movement, said panelbeing provided with an elongated slot to provide clearance for the meansconnecting the junction box with. the. lamp socket means.
